Koastal Eco Group closed out the challenging yet remarkable year of 2021 with outstanding results, achieving nearly VND 600 billion in revenue and, most notably, successfully completing and handing over two wastewater treatment projects for the TH True Milk Dairy Farm No. 3 in Nghe An and the Newhope Swine Farm in Binh Phuoc.
Both systems achieved treated effluent quality meeting Column A requirements (Kq = Kf = 0.9) under QCVN 62-MT:2016/BTNMT, exceeding the original requirements specified for the projects.
According to the Environmental Impact Assessment (EIA) reports, both projects were initially required to treat wastewater to Column B under QCVN 62-MT:2016/BTNMT. However, driven by the strong environmental commitments of the two Investors, TH Group and Newhope, toward sustainable development, together with their confidence in the capabilities and commitments of Koastal Eco Group, both projects were required to achieve Column A standards instead of Column B as originally specified in the EIA.
This requirement represented both a great honor and a significant challenge for the Koastal Eco team. At that time, there were no large-scale livestock wastewater treatment systems in Vietnam — and even globally — that had demonstrated the ability to consistently meet such stringent requirements.
After 12 months of commissioning and optimization for the TH dairy farm wastewater treatment system and 8 months for the Newhope swine farm system, the systems underwent 12 rigorous rounds of sampling and testing conducted by the Investors and relevant authorities.
In December 2021 and January 2022, Koastal Eco Group was honored to receive approval from both Investors, TH and Newhope, for the official acceptance and handover of the systems. The treated effluent consistently achieved Column A requirements under QCVN 62-MT:2016/BTNMT, in accordance with the signed contracts, while maintaining reasonable operating costs and stable treatment performance.
To achieve these results, Koastal Eco Group applied proven biological treatment technologies, combining CSTR anaerobic treatment with an Oxidation Ditch aerobic treatment process to effectively remove biodegradable organic pollutants from manure-rich livestock wastewater.
This treatment approach offers several advantages. The systems require lower chemical consumption, while the resulting sludge can be collected and transferred to an organic fertilizer production line when meeting the necessary conditions. This creates an additional potential revenue stream for the Investor while reducing the cost of excess sludge management at the WWTP.
Another outstanding feature of the technology designed by Koastal Eco is its significantly lower land requirement, using only approximately 20–30% of the land area required by conventional biogas-based treatment systems. This allows Investors to allocate more land for livestock facilities and, where necessary, develop additional feedstock production areas.
To date, Koastal Eco Group is proud to have successfully completed and handed over two livestock wastewater treatment projects — one for dairy farming and one for swine farming — achieving Column A under QCVN 62 while maintaining reasonable operating costs.
These achievements serve as strong evidence of Koastal Eco Group’s capabilities in research and development, the application of advanced and challenging treatment technologies, and our long-term commitment to environmental protection in Vietnam.
This is particularly meaningful for industries characterized by highly polluted wastewater streams, such as livestock farming, where effective and sustainable wastewater treatment remains a major environmental challenge.
With these achievements as a strong foundation, we believe that the entire Koastal Eco Group team will continue working together to accomplish even greater goals and overcome new challenges in 2022.
